It should right? And would there be much difference from stock?

ZR1 cam will fit in an LS2. However there are other/better choices unless you are planning for a future supercharger application. Even then there are plenty of choices.

yes the cam is set up for a charger. you will not get what you looking for unless you add one, without a charger you might loose power

What company does Patrick Robers work for?

Patric roberts worked for a place in dallas called regal performance. the owner ron at ragal performance is a cool dude and help me out as much as opssible with the tool named patric. I know he will be tring to work as an engine builder or something like that. i looked into his past with my lawyer and he has done this in the past. he even was put into the hospital for doing this to another guy. so he will be in a 100 mile radius around dallas area. need any more info?

Absolutely. I am running one right now in my 684RWHP / 580RWTQ build. It is quite similar to the LS7 cam but with more duration on the exhaust. It is an OEM camshaft, so obviously it won't net the biggest power gains, but you can expect to see some increase on an N/A car (my ballpark guess: 15-ish WHP on a car that has headers) and good gains on a boosted car (40 - 60WHP depending on how extreme the build is). I know a guy making 801RWHP with a ZR-1 cam.

You can make a lot more from a bigger cam, BUT, it is an OEM cam so it doesn't drive "like stock": it IS stock. My car starts up idles and drives exactly like it did from the factory. For guys like me who hate cam lope/surge it is the way to go. Also the fact that it is dirt cheap ($150 bucks) doesn't help either.

I strongly suggest pairing it up with a set of valvesprings. That has the added advantage of allowing you to rev higher (I spin mine to 7200RPM though as with most stock manifold engines power does begin to trail off a bit after about 6600).
